Uploading an image as a task attachment has resulted in the image displaying multiple times when viewing the task:

After deleting just one of them, an attempt to delete any of the others results in a message in a little red box (sorry but it will only let me embed a single image) that says:

Error: Request failed with status code 404 The task attachment does not exist.

Logging out and back in to either the desktop app or the web interface doesn’t change anything - these rogue entries are still shown.

I’ve just tried deleting 3 of the entries and all three are showing the same ID’s in the log:

The `FileID: 0` part looks odd.

Does this happen every time you upload an attachment?  
Can you reproduce this on [try](https://try.vikunja.io)?

No I can’t. Going back to the tasks that were showing rogue entries… they’ve now gone. Possibly some strange caching issue. I’ve just tried attaching a file to another task. It shows 1 attachement. If I come back out of the task then click on it, it shows 2. Out and back in again and there’s 3… and so on. So I’m guessing the first time I delete it, it works - after that it fails because the attachments aren’t actually really there even though they’re still displaying. I have a nginx reverse proxy in front of it so maybe I’ll take a look in there

I generally use nginx as a security layer and serve any http content up from apache. The relevant location blocks in nginx are as follows:

```nginx
    location ~* ^/(api|dav|\.well-known)/ {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://localhost:3456;
    client_max_body_size 20M;
    }

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_max_temp_file_size 0;
        proxy_buffers 16 16k;  
        proxy_buffer_size 16k;
        proxy_pass http://127.0.0.1:8080;
    }

```

and apache 2 is as follows:

```apache
    RewriteEngine On
 	RewriteRule ^\/?(favicon\.ico|assets|audio|fonts|images|manifest\.webmanifest|robots\.txt|sw\.js|workbox-.*|api|dav|\.well-known) - [L]
    RewriteRule ^(.*)$ /index.html [QSA,L]
    <Directory /var/www/tasks.example.com/html>
        Options -Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require all granted

    </Directory>

    SetEnvIf X-Forwarded-Proto "https" HTTPS=on

    RemoteIPHeader X-Forwarded-For
    RemoteIPTrustedProxy 127.0.0.1

```

Can you spot anything wrong here? Other than this issue it all appears to be working ok.

I’m not sure if this is related to using apache and nginx the way you do. It looks like you used the apache2 config from the proxy + frontend host example. Try [this one](https://vikunja.io/docs/install-frontend/#apache) which is for hosting just the frontend.

What version are you using?

Of vikunja? I only downloaded it last week so I imagine the most recent unless something else has been released since. I’ll try tinkering with that apache config and report back.

And what version did you download?

You can check this in the about dialog in the frontend.

Both frontend and API are v0.18.1
